An improved battery level indicator is provided. A first portion of the battery level indicator can be filled with a first color to indicate a charge level or remaining power level of a battery. A second portion of the battery level indicator can be filled with a second color to indicate a discharge level or consumed power level of the battery. As the battery power continues to be consumed, the battery level indicator re-colors both portions of the battery level indicators periodically with the first and second colors. In some implementations, a small gap portion can be displayed between the two portions described above, and the small gap portion can be filled with a third color, with a color intensity level in between the first and second colors.

CROSS-REFERENCES TO RELATED APPLICATIONS

The present application is a continuation of U.S. Nonprovisionalapplication Ser. No. 14/994,154, filed Jan. 13, 2016, which claims thebenefit of priority to U.S. Provisional Application No. 62/273,262,filed Dec. 30, 2015, the contents of which are hereby incorporated byreference in their entirety for all purposes.

FIELD

The present invention battery power indicator and, more particularly, tobattery level indicator which can indicate an amount of battery powerthat has been consumed and an amount of battery power still remains in abattery.

BACKGROUND

A conventional battery power indicator typically indicates how muchpower left in a battery. The convention battery power indicator istypically displayed in a shape of an actual battery, with a portion ofthe battery shape being colored to indicate a remaining battery powerlevel. For example, when the remaining battery power is between 60% to100%, the conventional battery power indicator typically colors acorresponding portion of the battery shape with green; when theremaining battery power is between 20% to 60%, the conventional batterypower indicator typically colors the corresponding portion of thebattery shape with yellow; and when the remaining battery power is lessthan 20%, the conventional battery power indicator typicallycorresponding portion of the battery shape with red. One drawback withthe conventional battery power indicator is while it indicates theremaining battery power and relative strength of the battery power untilnext charge with colors, it does not clearly indicate a progress ofbattery progress consumption.

BRIEF SUMMARY

Embodiments can facilitate a dynamic display of battery level. Thepresent disclosure provides an improved battery level indicator bycoloring the remaining battery power portion of the indicator with afirst color and coloring the consumed battery power portion of theindicator with a second color. As the battery power continues to beconsumed, the battery level indicator re-colors both portions of thebattery level indicators periodically with the first and second colors.This creates a visual effect that can show a progress of batteryconsumption, i.e., a rate at which the battery is being consumed. Insome implementations, a small gap portion can be displayed between thetwo portions described above, and the small gap portion can be filledwith a third color, with a color intensity level in between the firstand second colors. This small gap portion of the indicator can serve asa visual cue to indicate where the battery power relative to the entirebattery power originally in the battery.

DETAILED DESCRIPTION

In the following description, various embodiments will be described. Forpurposes of explanation, specific configurations and details are setforth in order to provide a thorough understanding of the embodiments.However, it will also be apparent to one skilled in the art that theembodiments may be practiced without the specific details. Furthermore,well-known features may be omitted or simplified in order not to obscurethe embodiment being described.

A battery level indicator in accordance with the disclosure can have acolor indicating a level of battery power remaining in the battery andanother color indicating a level of battery power that has been consumedthus far. In some embodiments, the display of battery power remaining isadjacent to the display of battery power that has been consumed thusfar. To achieved this, a portion of battery power remaining in thebattery level indicator can be filled with a first color and a portionof battery power consumed in the battery level indicator can be filledwith a second color. The first color and the second color can bedifferent. In some embodiments, none of the first and second colors isblack or white. The display of battery remaining and consumed may beupdated periodically to reflect a progress of battery consumption. Asthe battery power continues to be consumed, the portion of the batterypower consumed in the battery level indicator can appear to push theportion of battery power remaining in the battery level indicator, andmay provide a progress of battery consumption—i.e. how fast the batterypower is being consumed.

FIG. 1 illustrates some examples of a battery level indicator 100 inaccordance with the disclosure. As shown, the battery level indicator100 can visually provide battery consumption information for battery108, which in some examples can be a “smart battery”. A smart batterytypically can have a built-in battery management system (BMS). Thus inthose example, battery 108 can internally measure voltage and current,and determine various parameters of the battery. The parametersdetermined by the battery 108 in those examples can include voltage,temperature, state of charge or depth of discharge, state of health,current, and/or any other parameters. The values of these parameters canbe communicated externally by the battery 108, e.g., to a processor orto a CAN bus, which can process these parameter values to implement thebattery level indicator 100 for display.

As illustrated in FIG. 1, the battery level indicator 100 can be in theshape of a bar. It should be understood this is not intended to belimiting. In some other examples, the shape of battery level indicator100 can be of various shapes, such as a circular ring, an open oval, anactual battery, or any other shapes. In any case, as shown, the batterylevel indicator 100 can have a portion 102 indicating a charge level orremaining power level of battery 108. As shown, the portion 102 can befilled with a first color. As also shown, the battery level indicator100 can have a portion 104 indicating a discharge level or consumedpower level of battery 108. The portion 104 can be filled with a secondcolor.

In FIG. 1, for illustration, the display of battery level indicator 100is illustrated at three time instants: T0, T1 and T2. At time T0,battery 108 is at full charge, and thus portion 102 occupies the entiredisplay area of the battery level indicator 100. As also shown, a smallgap portion 106 may be displayed next right to portion 102. There aretwo purposes of displaying the small gap portion 106. First the smallgap portion 106 can indicate there is potentially an error in thebattery power information visually displayed in battery level indicator100. As mentioned above, although a charge and/or discharge level can becalculated based on battery information provided by BMS, the accuracy ofthe battery information can vary. Sometimes there could be a smallpercentage or margin of error in the battery information provided byBMS. The small gap portion 106 can be used to indicate, more or less,the battery power is currently at a level indicated by the small gapportion 106. Second, the small portion 106 can give a cue where theremaining power is relative to the entire batter power so a user caneasily discern a progress of the battery consumption as time progresses.In implementations, the size of the small portion 106 can be howeverdesired, but preferably about 5% of the entire display area of batterylevel indicator 100.

As shown, at time T1, the battery charge level and discharge level isabout at 50% each. As a result, portion 104 is filled with a secondcolor to indicate a corresponding battery discharge level. At time T2,the battery charge level is at 40% and discharge level is at 60%. As aresult, portion 104 has grown, as compared to that at time T1, to occupymore display area in the battery level indicator 100. This progressivegrowth of portion 104 at different times, such as from time T1 to T2,can provide a visual effect reflecting a progress at which the battery108 is being discharged. In some implementations, the battery levelindicator 100 can be updated once every second or few seconds to reflectthe progress.

With illustration of exemplary battery level indicator having beendescribed, attention is now directed to FIG. 2, which illustrates ablock diagram of a processor configured to implement a dynamic batterylevel indicator 100 shown in FIG. 1. As shown in this example, theprocessor 200 may be configured to include a sampling component 202, apower ratio determination component 204, a color determination component206, a paint component 208 and/or any other components. The samplingcomponent 202 can be configured to periodically obtain batteryinformation from a BMS of a battery. For example, without limitation,the sampling component 202 may be configured to obtain the batteryinformation once every second. The battery information obtained by thesampling component 202 may include battery charge level and/or batterydischarge level at the time when the sampling component 202 obtains thebattery information from BMS. In some examples, the sampling component202 may be configured to decode the battery information received fromthe BMS to obtain the battery charge and/or discharge level values.

The power ratio determination component 204 can be configured todetermine a ratio between the current charge level and discharge levelof the battery based on the battery information obtained by the samplingcomponent 202 for a given time instant. For example, at the giveninstant, the sampling component 202 may obtain a particular value for acharge level of the battery and the total charge level of the battery.As another example, at the given instant, the sampling component 202 mayobtain a particular value for discharge level of the battery and aparticular value for the charge level of the battery. The power ratiodetermination component 204 may be configured to determine a ratiobetween the charge level and discharge level based on the aforementionedbattery information obtained by the sampling component 202. The ratiodetermined by the power ratio determination component 204 may be in theform of percentage, for example 10%, 20%, 30%, 40%, 50%, 60%, 70%, 90%,100%, or any other percentage numbers. The ratio determined by the powerratio determination component 204 can thus indicate a power level ofbattery relative to total power of the battery.

The color determination component 206 can be configured to determinecolors to be filled in a portion of battery level indicator indicating acharge level of the battery and a portion of battery level indicatorindicating a discharge level of the battery. The colors determined bythe color determination component 206 for these two different portionscan be different. For example, without limitation, the color to befilled in the portion of battery level indicator indicating a chargelevel can be blue, and the color to be filled in the portion of batterylevel indicator indicating a discharge level of the battery can be red.In some examples, the colors determined by the color determinationcomponent 206 may not be black or white, as those colors tend not toprovide a good visual to reflect a progress of battery consumption. Insome embodiments, the color determination component 206 can beconfigured to determine a color to be filled in a gap portion (e.g.,such as small gap portion 106 shown in FIG. 1) between the portion ofbattery level indicator indicating a charge level and the portion ofbattery level indicator indicating a charge level indicating a dischargelevel. The color determined for gap portion can be a color in betweenthe colors for the aforementioned two portions in terms of intensity andcolor value. For example, the color for the gap portion can be magenta.

In some examples, the color determination component 206 can beconfigured to change the colors of the portion of battery levelindicator indicating a charge level and/or the portion of the batterylevel indicator indicating the discharge level depending on batterypower level. For example, a threshold can be set such that once thebattery power drops below 20%, the portion indicating batteryconsumption can be colored with a color different from the colorpreviously filled in the portion indicating battery consumption. In thisway, it gives the user a visual cue to determine that the battery powerlevel is low.

The paint component 208 can be configured to paint the display area ofthe battery level indicator according to the power ratio determined bythe power ratio determination component 204 and the color valuesdetermined by color determination component 206. For example, withoutlimitation, the power ratio determined by the power ratio determinationcomponent 204 can be 30/70%, meaning there are 70% power still left inthe battery. In that example, the paint component 208 can determine that70% of the display area of the battery level indicator can be filledwith a first color value determined by the color determination component206 and that 30% of the display area of the battery level indicator canbe filled with a second color value determined by the colordetermination component 206. The frequency of the paint component 208paints the display area of the battery level indicator can be asfrequent as the power ratio determination component 204 determines thepower ratio. In some embodiments, the paint component 208 is configuredto re-paint the display area of the battery level indicator as soon as anew value of power ratio is received from the power ratio determinationcomponent 204.

Application of the battery level indicator in accordance with thedisclosure can be in a wide areas. For example, the battery levelindicator can be used on an electronic device that is connected to anexternal rechargeable battery, on a portable device such as mobile phonethat has an embedded rechargeable battery, or merely on a batteryitself. Among various applications of the battery level indicatorcontemplated, perhaps an important application of the battery levelindicator is in a driving apparatus. The driving apparatus can compriseone or more batteries, and derives some of all of its power from thebatteries. It is important for an operator of such a driving apparatusto be aware of the progress of battery consumption, i.e., a rate atwhich the batteries employed by the driving apparatus is beingdischarged, not just how much battery power is left. The battery levelindicator in accordance with the disclosure can aid the operator of thedriving apparatus to determine an approximate time frame in which thebatteries in the driving apparatus will be discharged to a low level andthus needs to be recharged. An illustration of battery level indicatorused in a driving apparatus is illustrated in FIG. 3.
